SODIUM BICARBONATE is used to treat soluble calcium in water based drilling fluids. It treats cement contamination, deflocculates contaminated fluids, calcium and reduces pH.
SODIUM BICARBONATE helps to prevent high pH and calcium concentrations in order to maintain polymer concentrations.
Sodium Bicarbonate is used in water-based drilling fluids for treating cement contamination, and for treating calcium contamination while drilling anhydrites.
The recommended treatment or pre-treatment is 0.5 ppb to 1 ppb Sodium Bicarbonate. If severe contamination has occurred, then start treating the mud system as above while performing pilot tests to determine the actual concentration required.
